Since you have the basics, expand on that. Build a more complex app that you would use. So pick out a hobby or something that interests you that an app would improve your experience with. Plan out the requirements/scope and start building it. Building any app you're going to run in to things that you won't find a tutorial for, or you might have to combine a few tutorials to create it. That's the best way to learn, is just taking on something and building it. If you don't have any ideas, ask a friend or family member if they could use an app. You'll learn even more if someone else is telling you what they need/wish it could do. Good luck expanding your skills.
